使用Postman将多部分/数据发布到Cakephp [英] Post multipart/data with Postman to Cakephp
问题描述
我目前正在CakePHP 3中构建RESTful API。我正在尝试通过Postman chrome扩展程序中的表格数据上传文件（包含一些其他数据）。但是，我不确定如何获取通过请求接收的数据。
公共函数add（）{
debug（$ this-> request-> input（））;
}
当我尝试调用debug时，给出了以下输出（$ this-> request-> input（））：
'------ WebKitFormBoundaryjQIb9c3vvKj8TzQ3

I'm currently building a RESTful API in Cakephp 3. I'm trying to upload a file (with some additional data) through form-data in the Postman chrome extension. However, I'm not really sure how I can obtain the data that is received through the request.
This is the data that I try to send to the pictures controller in the api folder with the following code:
public function add(){
debug($this->request->data);
$picture = $this->Pictures->newEntity($this->request->data);
if ($this->Pictures->save($picture)) {
$message = 'Saved';
} else {
$message = 'Error';
}
$this->set([
'message' => $message,
'picture' => $picture,
'_serialize' => ['message', 'picture']
]);
}
This throws a database error which says that I'm violating a foreign key constraint (I think this is because $this->request->data is empty). However, I only want to see how the posted data is looking but the $this->request->data doesn't show up when I try to output it with the debug() function. I tried to post a JSON body which actually does work. My question is how to get the data in the controller that is send through form-data.
edit
I did managed to output the request data which is indeed empty but $this->request-is('post') is true. When I try to output $this->request with debug() I get the following information:

Does anyone know what I'm doing wrong here? It seems like I'm receiving the text values but not the file that is also send. Besides that, I have still no idea how to obtain the data like the album_id and description.
edit 2 When I output $this->request->input() (without json_decode) with debug() I get the following output:
'------WebKitFormBoundarykeFhH2KM4LdYgsH0
Content-Disposition: form-data; name="album_id"
2
------WebKitFormBoundarykeFhH2KM4LdYgsH0
Content-Disposition: form-data; name="description"

------WebKitFormBoundarykeFhH2KM4LdYgsH0
Content-Disposition: form-data; name="favorite"
true
------WebKitFormBoundarykeFhH2KM4LdYgsH0--
'
My question is now how do I obtain the file that also send through the same request? (the last boundary seems empty)
I finally found the solution which is by calling debug($this->request->input()) (without json_decode). The problem was that Postman freezes when the file is very large (first I tried to upload a pdf document). Postman is not suited to output entire files. I had the following headers and body:
public function add(){
debug($this->request->input());
}
This gave the following output when i try to call debug($this->request->input()):
'------WebKitFormBoundaryjQIb9c3vvKj8TzQ3
